A VERY Big Mac! World's biggest McDonald's with 1,500 seats to be built for games.

The biggest McDonald's restaurant in the world will open for six weeks during the London 2012 Olympic games. More than 50,000 Big Mac burgers and 180,000 portions of fries will be served from the outlet in Stratford, east London. The huge temporary branch will have seating for 1,500 customers and will employ more than 2,000 staff.

While the world's top athletes compete at the Olympics and Paralymics from July 27 to September 9 three million people are expected to visit the McDonald's branch. The 3,000 square-metre restaurant built from recyclable materials will stretch over two floors and is equivalent to half the length of an American football field. The 12,000 people who applied to work at the huge branch and three others planned for the Olympic site have been put through X Factor style auditions across the country.

They were judged on politeness and how well they flipped burgers, served ice cream and cooked the French fries. McDonald's began its involvement with the Olympics in 1968 when the company airlifted hamburgers to U.S. athletes competing in Grenoble, France. The firm first became an official sponsor at the 1976 Olympic Games in Montreal and in 1984 McDonald's footed the bill for the Olympic swimming stadium in Los Angeles. The London Olympics will be the ninth games where McDonald's has acted as the event's official restaurant and the only branded food retailer feeding the athletes. Usain Bolt, the world's fastest man who won gold at the 100 metres in Beijing in 2008, claimed that chicken McNuggets were key to his success.
